Researchers have developed Neural Bayesian Anomaly Mitigation (NBAM), a novel loss function designed to improve the robustness of supervised machine learning models against data contamination. NBAM not only makes models tolerant to corrupted data, similar to existing robust losses like Huber or Student's t-test, but also functions as an unsupervised classifier to identify which specific observations are corrupted. The method utilizes a Bayesian latent-switch mixture model to achieve this, outperforming baseline robust losses on the CIFAR-10 dataset with significant contamination rates. AI
